1. PURPOSE

The Purpose of this document is to describe the Release Delivery effects on the relevant partiesand the new and changed functionalities that installing this Release Delivery bring to thecustomer’s network.

2. RELEASE DELIVERY EFFECT

WN6.0 MP4.2 BTS software package delivery contains:• Over 80 corrections• No new features

All corrections are listed on Change Note document.

3. EFFECTS ON END-USER

The main effects are more detailed in next chapter.Those are improving end-user experience basically in all functional area

• Improved set-up success rate• Better service availability (Cell availability, BTS and unit stability)• Better retainability• Better HSPA service• Improved operability for a operator

NOTE:

During the pilot were noticed HSPA accessibility failures due to BTS in heavyloaded 4+4+4 configuration sites.

The customers who have 4/4/4 configuration deployments should take thecoming release WN6.0 MP4.21, which will have correction for this problem .

4. MAIN FLEXI BTS CORRECTIONS

4.1 Set-up and access

Main corrections:• RAB Access Fail CS Voice MS M1001C122

4.2 HSPA

Main corrections for HSPA:• Flexi BTS without HSDPA traffic after transmission break• FXDA type B configuration throughput is 500 kbps for HSUPA•

Increase of HSUPA access failures due to BTS after MP4.1 SW upgrade• Throughput impacted while HSDPA and HSUPA performed simultaneously• Poor HSUPA KPI due to lots of faults (493) “HsupaL2HwModificationRejected”

4.3 Stability

Main stability corrections:• BTS autonomous reset as recovery action (1811)• FSPC unit autonomous reset as recovery action after module unblock• FSPC autonomous restart due to 418 alarm• Recovery action doesn´t work after FSP failure in FSMB• Missing CEs in some Flexi sites with FSMB• Missing CEs after recovery reset of FSPC1• Extension module not detected in FSMB+FSMB configuration after MP4.0/MP4.1 SW upgrade

4.4 Antenna line

Main antenna line device corrections:• Missing RET 1.1 Tilt parameters after SW upgrade/downgrade• Antenna Device Failure (10) fault, no connection to unit is not handled by FM for one of 7 RETs• RET Inversion between Sector 1 and 3 with WN6.0 MP4.1

4.5 Operability

Main antenna operability corrections:• BTS internal SW management problem from FTM

5. MAIN ULTRASITE CORRECTIONS

5.1 Cell availability

Main corrections:• Alarm "no connection to unit, WPA" causes site out of service after restart

5.2 HSPA

Main corrections for HSPA:• Alarm “Not enough resources” for commissioned HSUPA

5.3 Stability

Main stability corrections:• Sudden loss of channel elements on UltraSite after Iub break

6. PILOTING

6.1 Pilot area

Total amount of sites was 231 in the pilot area.

• Flexi Rel1 : 2• Flexi Rel2: 212• UltraSites : 17

6.2 Pilot period

First live sites upgrade was done January 19 th and performance follow-up done was done untilthe release date.

6.3 Pilot results

The KPIs remained on a good level after 2 nd pilot SW upgrade February 12 th. The performancewas at least on the same level as with reference SW, WN6.0 MP3.22.

Some improvements were visible:

• Serving Cell Change (SCC) failures due to BTS decreased• HSDPA/HSUPA radio link failures decreased• HSUPA PS radio link failures decreased

However, during the pilot were noticed HSPA accessibility failures due to BTS in heavy loaded4+4+4 configuration sites.

The 4/4/4 configuration correction will be made to WN6.0 MP4.21 SW.

The customers who have 4/4/4 configuration deployments should take MP4.21 SW.
